    Default Harmonic balancer bolt size - Port vs Stb

    Do you guys have different harmonic balancers depending on the rotation of the engine? I never noticed this until now as I needed to rotate both by hand to TDC. My port (standard rotation) engine has a "dished" balancer with 3/4" hex bolt which is easily accessible. My Stb engine has a flat face pulley and a recessed bolt which requires a thin wall socket.

    What size is that bolt? I did not have that size on board.

    MIne were recessed and the same both sides. Should have a two piece pully system, belt to RW pump and belt to alternator/FW pump, right? I recall turning these cranks with everything on. 1/2" rachet system.
